[jboss-user] [Beginners Corner] - JBoss goes down!

[nabieh]

Dears,
     We have an application that been used by a 600 users via netowrk connections over the country, at a time, not less than 150 users are online using the application, the main goal of the application is to be an interface for a huge database and oter network components, we are facing a strange behavior of the application server - JBoss, from time to time, it goes down and became unaccessible, and it seems that the application is not able to run any more. I monitored the logs and found lot of exceptions regarding JDBC result sets exceptions says: java.sql.SQLException: Exhausted Resultset, I am sure we are closing every single connection/statement/result set we used! Can any one advice me on this field? We are using DAOs for DB conections, we use JNDI for retrieving datasourses, we cach those common used info into memory, we are using HP servers which considered to be v. good machines. Any comment will be highly appreciated, thanks in advance.
Note: We have lot of those requests that waits for responses for a period of time, and lot of those requests beeing executed at a time all the day. Those requests goes to queues and wait for the reply as XML from other queues, we are using IBM MQ services.

Nabieh.
